Nūhou - Ua kau inoa ʻo Kina a me Rūsia i kahi ʻaelike no ka Power of Siberia-2 natural gas pipeline. Ua hōʻike ʻo Royal Steel Group i kona makemake e kākoʻo piha i ka hoʻomohala ʻana o ka ʻāina.

I Kepakemapa, ua kau inoa ʻo Kina a me Rūsia i kahi ʻaelike no ka Power of Siberia-2 natural gas pipeline. ʻO ka pipeline, e kūkulu ʻia ma Mongolia, manaʻo e hoʻolako i ke kinoea kūlohelohe mai nā māla kinoea komohana o Rūsia i Kina. Me ka hoʻolālā ʻana i ka mana hoʻoili makahiki o 50 biliona cubic mika, manaʻo ʻia e hana ʻia ma kahi o 2030.

ʻOi aku ka mana o Siberia-2 ma mua o kahi pipeline ikehu; he lever hoʻolālā no ka hoʻoponopono hou ʻana i ka ʻōnaehana honua. Hoʻohaʻahaʻa ia i ka hegemony ikehu o ke Komohana, hoʻonui i ka launa pū ʻana ma waena o Kina a me Rūsia, a hoʻoikaika i ka ikaika o ka ʻāina. Hāʻawi ia i kahi hiʻohiʻona kūpono o ka hui lanakila-lanakila ma kahi honua multipolar. ʻOiai ke alo nei i nā pilikia ʻenehana, geopolitical, a me ka kaiaola, ʻoi aku ka waiwai hoʻolālā o ka papahana ma mua o nā palena ʻoihana, e lilo i papahana ʻāina i ka hoʻolaha ʻana i ke kūkulu ʻana i kahi kaiāulu me kahi wā e hiki mai ana no ke kanaka. E like me kā Putin i ʻōlelo ai ma ke kau inoa ʻana, "E hoʻopaʻa pū kēia pipeline i kā mākou mau wā e hiki mai ana."

Ma ke ʻano he hui kalepa ʻē aʻe i loea i nā paipu aila a me ke kila kūikawā, ua komo nui ʻo Royal Steel Group i ka papahana "Power of Siberia 2" natural gas pipeline, ʻoiai e kākoʻo ana i ka hui pū ʻana o ka ikehu a me nā kulekele hoʻomohala kūloko ma waena o Kina, Rusia, a me Mongolia.

ʻEkolu ʻeleʻele welded nui anawaena carbon kila paipu

Hiki i ka Royal Steel Group ke hāʻawi i ka API 5L X80, API 5L X90, a me nā paipu kila 3PE.

ʻO ke kila X80 kahi hōʻailona no ke kila paipu ikaika kiʻekiʻe, e pili ana i ka API 5L 47th edition standard. Hāʻawi ia i ka ikaika haʻahaʻa haʻahaʻa o 552 MPa, kahi ikaika tensile o 621-827 MPa, a me kahi ratio hua-i-ikaika o 0.85 a i ʻole. ʻO kāna mau pōmaikaʻi koʻikoʻi aia i ka hoʻolālā māmā, ka paʻakikī maikaʻi loa, a me ka weldability optimized.

Loaʻa nā noi maʻamau:
ʻO ka Pipeline kinoea kūlohelohe Kina-Russia Hikina: Ke hoʻohana nei i ke kila X80 a puni, hoʻouna ʻo ia i 38 biliona cubic mika o ke kinoea i kēlā me kēia makahiki a hele i ka permafrost a me nā wahi hana seismically, e hoʻonohonoho ana i kahi pae honua no ka ʻenehana hana pipeline onshore.

Papahana Pipeline Gas III Komohana-hikina: ʻO nā paipu kila X80 ma mua o 80% o ka nui o ka hoʻohana ʻana, e kākoʻo ana i ka lawe ʻana i ke kinoea kūlohelohe mai ke komohana Kina a i ka ʻāina ʻo Yangtze River Delta.
Hoʻoulu ʻana i ka ʻaila hohonu a me ke kinoea: I loko o ka Liwan 3-1 gas kahua pāhana ma ke Kai Kina Hema, ua hoʻohana ʻia nā paipu kila ʻole X80 no nā paipu submarine ma ka hohonu o ka wai ma mua o 1,500 mika, me ka ikaika compressive waho o 35 MPa.

Hōʻike ke kila X90 i ke kolu o ka hanauna o nā kila paipu ikaika kiʻekiʻe, e hoʻokō me ka API 5L 47th edition standard. Loaʻa iā ia ka ikaika liʻiliʻi o 621 MPa, kahi ikaika tensile o 758-931 MPa, a me kahi kalapona like (Ceq) o 0.47% a i ʻole. ʻO kāna mau pōmaikaʻi koʻikoʻi ka mālama ʻana i ka ikaika kiʻekiʻe, ka weldability breakthrough, a me ka adaptability haʻahaʻa haʻahaʻa.

Loaʻa nā hihia noi maʻamau:

Mana o Siberia 2 Pipeline: Ma ke ano he kumu nui o ka papahana, e lawe ana ka paipu kila X90 i ka lawe kinoea loihi mai na kahua kinoea o Siberia Komohana o Rusia a i Kina Akau. Ma ke kauoha ʻana i ka makahiki 2030, manaʻo ʻia ka nui o ka hoʻoili kinoea makahiki ma mua o 20% o ka nui o ka lawe ʻana mai o ka pipeline a Kina.

Ka laina paipu kinoea kūlohelohe o Central Asia D: Ma nā wahi lepo paʻakai nui o ka ʻāpana Uzbek, X90 paipu kila, i hui pū ʻia me kahi ʻōnaehana pale cathodic 3PE +, ua hoʻonui ʻia kona ola lawelawe i 50 mau makahiki.

ʻO ka 3PE ka uhi ʻana me kahi epoxy powder coating (FBE) primer, kahi papa waena waena, a me ka polyethylene (PE) topcoat, me ka mānoanoa piha o ≥2.8mm, e hana ana i kahi ʻōnaehana pale "rigid + flexible":

ʻO ka papa kumu FBE, me ka mānoanoa o 60-100μm, hoʻopaʻa kemika i ka ʻili o ka paipu kila, e hāʻawi ana i ka hoʻopili maikaʻi (≥5MPa) a me ka pale disbondment cathodic (peel radius ≤8mm ma 65 ° C / 48h).

Hoʻopili waena: 200-400μm mānoanoa, i hana ʻia me ka resin EVA i hoʻololi ʻia, hoʻopili kino me FBE a me PE, me ka ikaika peel o ≥50N / cm e pale ai i ka hoʻokaʻawale interlayer.
ʻO waho PE: ≥2.5mm mānoanoa, i hana ʻia me ka polyethylene kiʻekiʻe (HDPE), me kahi Vicat softening point ≥110 ° C a me ke kūpaʻa ʻelemakule UV i hōʻoia ʻia e ka hoʻāʻo ʻana o ke kukui xenon arc 336-hola (ka hoʻopaʻa ikaika tensile ≥80%). He kūpono no ka hoʻohana ʻana i nā mauʻu Mongolian a me nā wahi permafrost.

ʻO ka Royal Steel Group, me kāna misionari o "Material Innovation Driving the Energy Revolution," hoʻomau i ka hāʻawi ʻana i nā huahana paipu kila hilinaʻi kiʻekiʻe a me nā lawelawe ʻenehana no ke kūkulu ʻana i ka ikehu honua.
